Answer 1

在`MainApplication.java 中替换此代码

@Override
protected String getJSMainModuleName() {
return "src/index"; <---add this
}

Answer 2

对于IOS

// packages/myapp/ios/myapp/AppDelegate.m:56
return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"src/index" fallbackResource:nil];

Answer 3

显然，将index.js移动到src/index.js有问题。我把它移回了项目根目录，现在它运行得很好。

Answer 4

通过删除和创建新的android模拟器来解决。。。

Answer 5

我得到了同样的错误，但在我yarn global remove wml之后一切都很顺利

yarn global remove wml

拯救了我的生命

如果您从未安装过wml，只需考虑其他一些相关的全局libs

----更新-----即使我卸载了wml工作人员，我也再次出现错误，但我发现问题的根本原因是watchman，在运行brew uninstall watchman后，一切正常

Answer 6

运行的远程调试器的一个旧实例导致了我的这种情况；"为什么"；，但是，如果您想以编程方式终止调试器，请将其添加到App.tsx的顶部，或者添加到任何顶级入口文件中：

import { NativeModules } from 'react-native';
NativeModules.DevSettings.setIsDebuggingRemotely(false);

Christophe Marois回答了这个问题如何在React Native 中禁用远程JS调试

Answer 7
